FEED-WATER HEATING AND PURIFYING APPARATUS.

SPECIFICATION forming part Of Letters Patent No. 471,521, dated March 22, 1892.

Application filed December 12, 1891. Serial No. 414,900. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL W. MCCALLUM, a citizen of the United States, residing at Forth Worth, in the county of Tarrant and State of Texas, have in vented certain new and useful Improvements in Feed-VVater Heating and Purifying Apparatus, of which the follow- I ing is a full, clear, and exact specification.

This invention has for its object to provide novel, simple, efficient, and economical means for utilizing the heat of exhauststeam from locomotive-cylinders and the waste heat from the products of combustion in the combustion-chamber or smoke-arch for heating and purifying the feed-water in transit to the 10- comotive-boiler.

To accomplish this object my invention involves the features of construction and the combination or arrangement of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a sectional side elevation showing suificient of a locomotive-boiler to illustrate my invention. Fig. 2 is a vertical sectional view taken on the line a: m, Fig. 1.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The letter A indicates a water-tank composed of boiler metal and resting on a saddle or other suitable support R between the two locomotive-cylinders N, which are supplied with live steam from the boiler through the medium of pipes K. The top wall of the wa tertank is formed with a concaved seat which constitutes a solidbearing for the forward portion of the boiler, which portion is constructed with the usual combustion-chamber or smoke-arch E.

The exhaust-steam pipes F of the locomotive-cylinders extend through the water-tank and communicate with the lower portion of the combustion-chamber or smoke-arch, and from one exhaust-pipe extends a branch L, adapted to connect with the tender and provided with a valve], so that by opening such valve and closing the valve M of the exhaust flow to ,the tender for warming the water therein. 1

The water-tank is provided'at its'rear with a pipe 0 for introducing the feed-water, and the front portion of the water-tank is in practice provided with man-holes for cleaning the tank when necessary. It is not deemed essential to illustrate the man-holes, as they may be constructed and arranged in any manner suitable for the conditions required.

In the combustion-chamber or smoke-arch is located a series of water-tanks, preferably three in number, B, C, and D, which are arranged one above the other. The lower water-tank B communicates with the water-tank A through the medium of a suitable pipe G, while the tank B communicates with the tank 0 through the medium of a pair of pipes H,

and the tank 0 connects with the upper tank D by means of a pipe I. The upper tank connects with the boiler by a pipe J, having a suitable valve for controlling the passage of ter is heated to a certain degree, and sediment settles in such tank. The heated feed water rises through, the pipe Ginto the lower water-heating tank B, and thence to the upper water-heating tanks 0' and D, as will be obvious. The water as it passes from tank to through the water-tank the water in the lattank is gradually heated to a-higher temperature and sediments and impurities settle at the bottom of each tank, so that the feed-water finally passes to the boiler, through the pipe J, in a comparatively pure condition at a temperature of 212 degrees Fahrenheit.

The invention provides a simple, efficient, and economical apparatus'for heating and purifying .the feed-water of a locomotiveboiler, and the parts are so constructed and arranged as to utilize the heat of the exhauststeam as well as the Waste heat of the products of combustion in the combustion-chamber or smoke-arch of the boiler.

Having thus described my invention, what I claim is 1. The combination, with a locomotiveboiler having at one end a combustion-chamber or smoke-arch, of a water-heating tank having a top wall bearing against and supporting the combustion-chamber or smokearch, a feed-water pipe opening into the tank, and exhaust-steam pipes leading from the 10- comotive-cylinders, extending through the water-tank, and opening into the combustionchamber or smoke-arch, substantially as described. I

2. The combination, with a locomotiveboiler having at one end a combustion-chamber or smoke-arch containing a water-heati ng tank, of a feed-water-receivin g tank located in juxtaposition to the combu tion-chamber or smoke-arch, a pipe connecting the said feed- Water-receiving tank with the Water-heating tank in the combustion-chamber or smokearch, and exhaust-steam pipes leading from the locomotive-cylinders, extending through the feed-Water-receiving tank, and opening into. the combustion-chamber'or smoke-arch, substantially as described.

3. The combination, with a boiler having at one end a combustion-chamber or smoke-arch, of a series of water-heatin g tanks arranged in the combustion-chamber or smoke-arch and having pipe connections with each other, a feed-water-receiving tank located in juxtaposition to the combustion-chamber or smokearch and provided with a feed-Water pipe, a pipe connection between the feed-water-receiving tank and one of the water-heating tanks, and exhaust-steam pipes leading from the locomotive-cylinders into the feed-waterreceiving tank and communicating With the combustion-chamber or smoke-arch, substantially as described.

4. Thethree Water-tanks B O D of boilermetal, constructed with rounded bottoms, man-holes at the front side and arranged in the combustion-chamber or smoke-arch one above the other and connected each With the other by means of pipes, the upper tankD beiug connected with the boiler, substantially as described.
